MY First Package/Proc

Question

Hello, It has been a couple of years since I took and Oracle class, so I am a bit rusty. I am trying to figure out the syntax on how to create the body of a package. My "Procedure" is very simple, read in a couple of parms and output some fields (multi row select). I got the "package" portion, to compile and it looks like the following:
CREATE OR REPLACE PACKAGE OPS_UI_QUERIES IS
PROCEDURE QRY_HIGHLIGHTS(i_Product_ID           IN OPS_Milestones.PRODUCT_ID%TYPE,
                              i_Time_ID     IN ops_Milestones.TIME_ID%TYPE,
o_Milestone_ID      OUT OPS_Milestones.MILESTONE_ID%TYPE,     o_Product_ID     OUT OPS_Milestones.PRODUCT_ID%TYPE,     o_Time_ID     OUT OPS_Milestones.TIME_ID%TYPE,
o_Catagory_ID     OUT OPS_Milestones.CATAGORY_ID%TYPE,
o_Sort_Order     OUT OPS_Milestones.SORT_ORDER%TYPE,
o_Last_Update_DTTM OUT OPS_Milestones.LAST_UPDATE_DTTM%TYPE);     
END;
So I have input values and output values.
When I define a cursor...do I also define all of the input and output values within the Parenthesis, like the following?
CREATE OR REPLACE PACKAGE BODY OPS_UI_QUERIES
IS
PROCEDURE QRY_HIGHLIGHTS (          
CURSOR c_Highlights
(i_Product_ID IN OPS_Milestones.PRODUCT_ID%TYPE,
i_Time_ID     IN ops_Milestones.TIME_ID%TYPE,
o_Milestone_ID OUT OPS_Milestones.MILESTONE_ID%TYPE;
) IS
select om.MILESTONE_ID
from ops_Milestones om
where product_id = i_Product_ID
and time_id = i_Time_ID
and deleted is null
order by sort_order;
AS
BEGIN
OPEN c_Highlights
FETCH c_Highlights INTO     
o_Milestone_ID
EXIT WHEN c_Highlights%NOTFOUND;
RETURN o_Milestone_ID;
END;
END:
Do I have to place the output variables into a "DECLARE" section?
Will this return all the rows with "o_Mileston_ID"?
Im's sure there are easier ways to do this with a Cursor record, but I want to first do it the "hard way" and then come back an learn the easier way.
Thanks in advance for all of your assistance!!!

Answer 1

Do I have to place the output variables into a "DECLARE" section <<No, output variables are declared in the parameter list. A corresponding variable must exist in the caller.
Will this return all the rows with "o_Mileston_ID"? <<No, look up reference cursors. You need to ensure you close your cursor also. Procedures do not use the RETURN clause, functions do.
As written your procedure would read one row. You need a loop.
Either read the full pl/sql manual or buy a book on Pl/SQL. Connor MacDonnell wrote one that should be worth reading.
